摘要

舌像分割中嘴唇和舌体部分的纹理和颜色比较接近，直接采用Snake方法提取舌体轮廓很难得到理想的轮廓。本文提出一种结合径向边缘检测与Snake模型的分割方法，首先使用径向边缘检测得到初始轮廓，使用色彩对消消除嘴唇影响，最后用Snake获取舌体轮廓。实验表明该算法取得较好的分割效果。

Abstract

Because the texture and color the tongue and the lip is very close

it is difficult to extract the accurate contour of the tongue body only with the active contour model： Snake.This paper introduces a method that combines radial edge detection with Snakes model to solve this problem.Firstly

we use radial edge detection to get rough contour of the tongue.Then

we use pair-color-remove to remove the lip.Finally

we use snake to get the exact contour of the tongue. The experiment results are satisfying.
